This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting

Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Summary

This study will follow 10,000 adults with common joint or tendon problems—like knee arthritis, tennis elbow, or plantar fasciitis—who choose to receive a platelet-rich plasma (PRP) injection. PRP is made from a patient's own blood, spun to concentrate healing factors. Participants will report their pain and function over one year to see if the treatment helps.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Platelet-rich plasma (PRP) injection
What this could lead to
If successful, this study could show that PRP injections provide meaningful pain relief and improved function for common joint and tendon conditions.
What could go wrong
This is an observational registry, not a controlled trial, so results may be influenced by natural recovery or placebo effects. PRP is not yet proven to be better than standard treatments.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 10,000 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2025

Expected to finish

Jan 2035

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
